This doesn't really belong here, but I think more people read this than the Home Page.
I recently had to reset my password, but kept getting a notice that my password was not correct, I sent three e-mails trying to get it reset.
What I found out is that regardless of what password you used in the past, the password is now your membership number.
After finding this out, I did see that it is mentioned on the homepage.
Hopefully this will save someone the trouble of wondering why their old password doesn't work.
